  • Patent number: 8763930
    Abstract: The present invention's nozzle is especially suitable for use in a shipboard air-discharge maneuverability device known as a “bow thruster.” As typically embodied, the inventive nozzle includes a nozzle wall and an arc-shaped vane. The nozzle wall has a circular nozzle inlet and an elliptical nozzle outlet, and is configured so that the geometric major axis of the nozzle outlet is horizontal. The arc-shaped vane: is upwardly bowed in the nozzle wall's transverse direction; joins the nozzle wall along its two horizontally opposite sides in the nozzle wall's longitudinal direction; extends most or all of the longitudinal distance between the nozzle inlet and the nozzle outlet; has a transversely intermediate section that, taken in the transverse direction, is generally uniform in thickness; has two transversely lateral sections that, taken in the transverse direction, gradually thicken toward the two respective joints of the arc-shaped vane with respect to the nozzle wall.

  • Publication number: 20130179773
    Abstract: The present invention discloses a method for, online editing and publishing and the device thereof. The method for online editing and publishing comprises the following steps: obtaining from a storage unit or from the Internet, at least one figure with first configuration data; editing the at least one figure in an area of a web page, wherein the web page has at least one tool around the area for editing; generating a first drawing result from the editing; and publishing the first drawing result to the Internet through the web page of a website. With the present invention, the process of generating works may be simpler and faster than before; thereby the efficiency of work output and the number of works are increased.

  • Publication number: 20080076076
    Abstract: In one embodiment, a method of manufacturing an integrated circuit that comprises forming a circuit layer over a substrate, forming a resist layer on the circuit layer, and subjecting the resist layer to a rework process that includes exposing the resist layer to an organic wash. In another embodiment, the method of manufacturing an integrated circuit comprises forming a circuit layer over a substrate, forming a priming layer on the circuit layer, and subjecting the resist layer to the rework process. The reworking process includes exposing the substrate to a mild plasma ash to substantially remove portions of the resist layer but leave the priming layer.

  • Publication number: 20020086242
    Abstract: Wafer developer solution is removed in a wafer spinning process wherein the wafer is spun for a period of time before a deionized water bath is introduced. The delay allows more developer to be spun off before introducing the water, which eliminates residue and particulates on the wafer surface.

  • Patent number: 6386830
    Abstract: A high-pressure vane-axial fan assembly is provided. A rotor assembly has a plurality of rotor blades disposed circumferentially around and extending radially outward from a hub. Each rotor blade has an airfoil cross-section and is constructed to define a straight-ruled leading edge that extends outward from the hub. The rotor blade is rotated along its span relative to the straight-ruled leading edge. The plurality of rotor blades defines a solidity of greater than 1. A stator assembly has a plurality of stator vanes disposed circumferentially around and extending radially from the frame. There are a lesser number of stator vanes than rotor blades. The stator assembly is positioned adjacent the rotor assembly such that an axial gap is defined between the trailing edge of the rotor blades and the leading edge of the stator vanes. The axial gap increases with radial distance from the hub as defined by the shape of the trailing edge of the rotor blades and the shape of the leading edge of the stator vanes.

  • Patent number: 6382912
    Abstract: A centrifugal compressor or pump has a vaneless diffuser within which a radially extending passage is formed between a fixed plate surface and a profile contoured shroud surface establishing a pinch point location of minimum passage area intermediate inlet and outlet ends of the diffuser passage. Convergent and divergent flow portions of the diffuser passage respectively extend to and from the pinch point to establish continuous convergent flow from the inlet end and divergent flow toward the outlet end for exit outflow at a flow angle less than that of a convergent inflow angle from the inlet end imposed along an initial profile segment.

  • Patent number: 5490004
    Abstract: A liquid crystal light valve device exhibiting improved performance capabilities fabricated using a cadmium telluride light blocking layer doped with nitrogen. Because of the incorporation of nitrogen into the cadmium telluride light blocking layer, the layer can be applied using high-speed, low-cost sputtering techniques without resulting in excessive photoconductivity or photoshading. The cost of the addition of nitrogen is minimal. The process of the present invention is amenable to precise control and wide flexibility which results in control of the quality aspects of the light blocking layer such as particulate density.

  • Patent number: 5441776
    Abstract: A liquid crystal light valve that has an indium tin oxide (ITO) primary electrode disposed between two silicon dioxide bonding layers. The first bonding layer for bonding the primary electrode to a glass substrate and the second bonding layer for bonding said primary electrode to a hydrogenated amorphous silicon layer. The ITO primary electrode is sputtered which significantly reduces processing time and the silicon dioxide bonding layers allow the primary electrode to be bonded to the glass substrate and the hydrogenated amorphous silicon layer without peeling. For some applications the silicon dioxide bonding layer between the glass substrate and the primary electrode is not necessary.
